TRUE OR FALSE:

Question

A triangle can have sides of lengths 312, 54, and 262

Answer 1

'true

longest triangles side has to be shorter than the sum of the other two sides

that's satisfied. 312 is less than 54+262 = 316. that's an obtuse triangle

sum of any 2 sides must be larger than the 3rd side

shortest side has to be longer than difference of the other 2 sides

54 is greater than 312-262 = 50'

each triangle side must be greater than the difference of the other 2 sides

conditions are barely satisfied, which is what you get with a really obtuse triangle. a triangle with an angle greater than 90 is obtuse, 155 is greater than 90

or

just use a triangle solver on line. plug in the 3 sides. angles then are about 5, 155 and 20 degrees
